The R454B & R32 refrigerant sensor ZRT512E is an intelligent infrared refrigerant detection module. It utilizes the non-dispersive infrared (NDIR) principle to detect refrigerants, exhibiting excellent selectivity and no oxygen dependence. This module is a compact, high-performance unit created by tightly integrating a mature infrared absorption gas detection sensor with micro-machining and sophisticated circuit design. It is easy to use and offers superior performance.
